Function qt_core::q_variant_from_value

pub unsafe fn q_variant_from_value(
    t: impl CastInto<Ref<QVariant>>
) -> CppBox<QVariant>

Returns a variant containing a copy of the given value with template type T.

Calls C++ function: QVariant qVariantFromValue(const QVariant& t).

Warning: no exact match found in C++ documentation. Below is the C++ documentation for QVariant qVariantFromValue(const T &value):

Returns a variant containing a copy of the given value with template type T.

This function is equivalent to QVariant::fromValue(value).

Note: This function was provided as a workaround for MSVC 6 which did not support member template functions. It is advised to use the other form in new code.

For example, a QObject pointer can be stored in a variant with the following code:

QObject *object = getObjectFromSomewhere();
QVariant data = QVariant::fromValue(object);
